基于既有农村住宅能效提升的常规清洁取暖方式经济性分析
Economic analysis of conventional clean heating methods based on energy efficiency improvement in existing rural houses
摘要:
以承德市某典型农宅为例,以清洁取暖设备现场运行检测数据为依据,分析了农宅节能改造前后采用空气源热泵供暖系统或蓄热式电锅炉供暖系统2种形式下的供暖能耗、改造成本及运行费用。通过对比分析可知:该典型农宅采用空气源热泵供暖系统比采用蓄热式电锅炉供暖系统整个供暖季能耗可降低约52.5%;安装相同的供暖系统,若进一步对农宅进行能效提升,整个供暖季能耗可降低约28.7%,供暖季居民承担的运行费用可降低36.9%~50.8%;在对农宅进行清洁取暖改造的基础上同步开展农宅能效提升可以大幅度减少居民供暖成本。
Abstract:
Taking a typical rural house in Chengde as an example, the heating energy consumption, retrofit costs and operation costs before and after the energy-saving retrofit of the rural house are analysed based on the on-site operation test data of two different clean heating systems, namely the air-source heat pump heating system and the heat-storage electric boiler heating system. Through the comparative analysis, the energy consumption of the air-source heat pump heating system can be reduced by about 52.5% during heating season compared with that of the heat-storage electric boiler heating system applied to the same typical rural house in Chengde. If the rural house takes the energy-saving retrofit for further energy improvement, the heating energy consumption can be reduced by about 28.7% for both the air-source heat pump heating system and the heat-storage electric boiler heating system, and the operation costs of each heating season can be reduced by 36.9% to 50.8%. The heating operation costs can be reduced significantly by applying the clean heating renovation for heating system and the energy-saving retrofit on envelopes simultaneously.
